TRT-1R Touchscreen Room Thermostats

Description: TRT-1R smart thermostats feature a sleek flush-mounted slim design, ideal for controlling heating or cooling systems in various applications. Equipped with a 3.5” backlit color touchscreen, these thermostats offer intuitive control and modern aesthetics. They are suitable for zone control, underfloor heating/cooling applications, and can also function as lighting and/or air conditioning interfaces. The thermostats are compatible with Building Management Systems (BMS) or controllers via Modbus or BACnet communication interfaces.

Key Features:

  • Design: Modern flush-mounted slim design with a 3.5” backlit color touchscreen for intuitive control and aesthetics.
  • Versatile Applications: Suitable for heating or cooling control in various applications, including zone control and underfloor heating/cooling.
  • Compatibility: Can be connected to Building Management Systems (BMS) or controllers via Modbus or BACnet communication interfaces.
  • Relay Output: Equipped with a relay output (230 V, 7 A) for controlling heating or cooling systems.
  • Sensor Inputs: Two external NTC 10 sensor inputs for accurate temperature measurement. Resistive inputs can also act as potential-free contacts.
  • Digital Input: One digital input with potential-free contact for additional control options.
  • Supply Voltage Options: Available in 24 Vac/dc (22...28 V) or 90...250 Vac/dc supply voltage options.
  • Communication Protocols:
    • MOD models: Modbus RTU communication protocol with configurable parameters such as bus speed, parity, and stop bits.
    • BAC models: BACnet MS/TP communication protocol with configurable parameters such as bus speed, parity, and stop bits.
  • Display: 3.5" backlit touchscreen with a resolution of 320 x 480 pixels and support for 255K colors, providing clear and vibrant display of information.
  • Operating Conditions: Operates in temperatures ranging from 0 to 50 °C (32 to 122 °F) and humidity levels up to 95% RH (non-condensing).
  • Storage Conditions: Suitable for storage in temperatures ranging from -30 to 70 °C (-22 to 158 °F) and humidity levels up to 95% RH (non-condensing).
  • Wiring Terminals: Features tilted terminals for easy wiring, compatible with solid and stranded wires with sizes ranging from 0.05 to 2.5 mm² (solid) and 0.05 to 1.50 mm² (stranded).
  • Housing: IP20 protection class housing made of polycarbonate plastics, self-extinguishing for safety.
  • Mounting: Mounts on a flush mounting box with a 60 mm hole distance.
